Christ is an interminable well

Those of you who use the Treasury of Daily Prayer for you daily devotions read this wonderful quotation:

"The sun is not dimmed and darkened by shining on so many people or by providing the entire world with its light and bright splendor.  It retains its light intact.  It loses nothing; it is immeasurable, perhaps able to illumine ten more worlds.  I suppose that a hundred thousand candles can be ignited from one light, and still this lighty will not lose any of its brilliance.  Likewise, a learned man can educate a thousand scholars without forfeiting any of his own learning.  The more he shares with others, the more he has himself.  Thus Christ, our Lord, to whom we must flee and of whom we must ask all, is an interminable well, the chief source of all grace, truth, righteousness, wisdom, and life, without limit, measure, or end.  Even if the whole world were to draw from this fountain enough grace and truth to transform all people into angels, still it would not lose as much as a drop.  this fountain constantly overflows with sheer grace.  Whoever wishes to enjoy Christ's grace-- and no one is excluded-- let him come and receive it from Him.  You will never drain this fountain of living water; it will never run dry.  You will all draw from it much more than enought, and yet it will remain a perennial well."
